With all of the new crazy quoting shenanagains, I'm not sure that the
"balenced brackets are fine" rule will still be possible; and thus end
delimeters will always need to be escaped.  For instance, imagine
what a nightmare this would be to parse:

$var = qq[blah [\q[blah [\qq[%hash{qq[[hi]]}]]]] blah];

Sure, anyone who writes something like this deserves to be shot;
however, if the "balanced brackets are ok" rule still stands, the
above code would be legal.  (And I really, really, really don't
want the above code to be legal ;)
